Re: Scurvy & the Cruiser [Vitamin C]

Warfarin is an anticoagulant; not [technically] a “blood thinner’, because it does not reduce viscosity. It works, by reducing clotting proteins, in the blood.
As a vitamin K antagonist, Warfarin blocks the action of vitamin K, an important nutrient, for heart and bone health.

Yes but simple explanation easiest for multiple languages to understand when speaking to their physician about the medication and food interactions

Buying bread from a man in Brussels
He was six-foot-four and full of muscle
I said, "Do you speak-a my language?"
He just smiled and gave me a Vegemite sandwich
And he said

It's not what you might think. The drug was discovered by a researcher funded by the Wisconsin Alumni Research Foundation. The acronym is WARF. The common suffix for anticoagulants is -arin.
FWIW, the discovery was made by figuring out that cows that were bleeding to death were eating clover infected with a mold that produces the compound. Warfarin is a difficult medicine to use as the toxicity level is not that much higher than the beneficial level.

I am unaware of any evidence basis for this. Vitamin supplements are highly effective to provide vitamins that are missing from the diet. Yes, a broad-based diet, composed primarily of the least processed foods, is generally a great thing. If you have that kind of diet, no vitamin supplements are generally needed.

Two things to remember. First is that the main effect of vitamins is that they make your urine expensive. Most water soluble vitamins that are taken end up in the urine if they are not needed (and most people don't need most of them). But if you don't have a healthy, diverse diet with good amounts of fresh fruit, veg, and meat or meat substitutes, taking a multivitamin with normal doses (RDA) of vitamins will prevent the above listed vitamin deficiency disorders just as effectively as will the fresh food source. And buy them from the cheapest reputable source you can find. Think COSTCO or Target store brand, not the fancy label brands. Second is that vitamins can be toxic. Many people think that if a little is good, a lot is better. The mega vitamin fad was as inane as it was dangerous. For example, vitamin A can cause birth defects in pregnant women. Really bad ones. Again, just find an inexpensive but legit source of a standard dose multivitamin if you need one. Spending more money and having a cabinet full of various vitamins will get you nothing but expensive urine or worse.

Re: Scurvy & the Cruiser [Vitamin C]

Oh, and one more thing. Fresh citrus with an appropriate antibacterial compound such as C2H5OH is extremely effective. I tend to favor daiquiris but have lately switched to caipirinhas.

Re: Scurvy & the Cruiser [Vitamin C]

I suspect that mineral deficiency due to prolonged use of reverse osmosis water for tropical cruisers is at least as important as scurvy…..

Re: Scurvy & the Cruiser [Vitamin C]

I understand the most appropriate preventative for scurvy and stress-related lurgies is a daily double Gin and Tonic, with ice and a healthy slice of bitter lemon.


Optimally taken just as the sun goes down...

Re: Scurvy & the Cruiser [Vitamin C]

I've been on a intermiten fasting carnivore diet for two years. No scurvy, high blood pressure or any other problems, but still getting uglier and older. No cure for that.

Vitamin K works with vitamin D to regulate calcium in the blood and seems to help bone density.

Most/Many people are low in vitamin D. I have to take 5 times the RDA to get the vitamin D in my blood to about 70. One should be between 30 and 100. I am thinking about increasing my vitamin D intake to get to the upper range. Not sure the upper range is really what SHOULD be the upper limit....

Vitamin D is needed for bone health but also mental health a fighting off respiratory infections.

With a balanced diet no that is not an issue according the the WHO. they actually did a study on it.

It’s not so. According to this NIH study the contribution of drinking water to mineral nutrition is “small”:

https://www.ncbi.nlm.nih.gov/books/NBK216589/

In fact a lot of us are deficient in many minerals and vitamins, most of us in the case of vitamin D (and nearly all of us have insufficient):

"The percentage of individuals aged ≥2 y with total usual nutrient intake, including that from foods and dietary supplements, falling below the EAR was considerable for vitamin D (70%), vitamin E (60%), calcium (38%), vitamin A (34%), vitamin C (25%), and magnesium (45%)."

Fulgoni Ill, Victor L., et al. "Foods, fortificants, and supplements: where do Americans get their nutrients?." The Journal of Nutrition 141.10 (2011): 1847-1854.

I supplement with magnesium and potassium and vitamin C. I also make sure I get plenty of sun exposure for vitamin D (and infra red and nitric oxide benefits).

The guidelines are set to be sure to avoid illness, like scurvy or rickets, not for optimum health, so the guideline amounts should be seen as something approximating a minimum.

Re: Scurvy & the Cruiser [Vitamin C]

Fortunately, I absolutely LOVE cabbage in all its flavors. The Admiral stocks cases of chopped red cabbage and sour kraut. Scurvy is the least of my concerns....

Any concerns can easily be offset by frequent consumption of other water-containing liquids such as beer, wine and spirits!
